PASER Rating System

This chart describes the PASER rating system in detail and provides a description of the all the rating levels from 1 to 10 and what can be expected for each rating level.  Note that individual pavements will not have all of the types of distress listed for any particular rating.  They may have only one or two types.

Visible Distress General Condition / Treatment Measures
10 Excellent None New construction
9 Excellent None Recent overlay, like new.
8 Very Good No longitudinal cracks except reflection of paving joints.

Occasional transverse cracks, widely spaced (40' or greater).

Recent sealcoat or new road mix.  Little or no maintenance required.
7 Good Very slight or no raveling, surface shows some traffic wear.

Longitudinal cracks (open 1/4") spaced due to reflection or paving joints.

Transverse cracks (open 1/4") spaced 10 feet or more apart, little or slight crack raveling.

No patching or very few patches in excellent condition.

First signs of aging.  Maintain with routine crack filling.
6 Good Slight raveling (loss of lines) and traffic wear.

Longitudinal cracks (open 1/4" - 1/2") due to reflection and paving joints.

Transverse cracking (open 1/4" - 1/2") some spaced less than 10 feet.

Slight to moderate flushing or polishing.

Occasional patching in good condition.

Show signs of aging, sound structural condition.  Could extend life with sealcoat.
5 Fair Moderate to severe raveling (loss of lines and coarse aggregate).

Longitudinal cracks (open 1/2") show some slight raveling and secondary cracks.  First signs of longitudinal cracks near wheel path or edge.

Transverse cracking and first signs of block cracking.  Slight crack raveling (open 1/2").

Extensive to severe flushing or polishing.

Some patching or edge wedging in good condition.

Surface aging, sound structural condition.  Needs sealcoat or non-structural overlay.
4 Fair Severe surface raveling.

Multiple longitudinal and transverse cracking with slight raveling.

Block cracking (over 25 - 50% of surface).

Patching in fair condition.

Slight rutting or distortions (1" deep or less).

Significant aging and first signs of need for strengthening.  Would benefit from recycling or overlay.
3 Poor Closely spaced longitudinal and transverse cracks often showing raveling and crack erosion.

Block cracking over 50% of surface.

Some alligator cracking (less than 25% of surface).

Patches in fair to poor condition.

Moderate rutting or distortion (1" or 2" deep).

Occasional potholes.

Need patching and major overlay or complete recycling.
2 Very Poor Alligator cracking (over 25% of surface).

Severe distortions (over 2" deep).

Extensive patching in poor condition.


Severe deterioration.  Need reconstruction with extensive base repair.
1 Failed Severe distress with extensive loss of surface integrity. Failed.  Needs total reconstruction.

Note:  Individual pavements will not have all of the types of distress listed for any particular rating.  They may have only one or two types.
